摘要
为了设计磁悬浮系统的单磁体控制器,必须建立系统的状态空间模型。分析了磁悬浮系统的工作原理,结合经典动力学和电磁学基本理论,利用Lagrange方程的一般形式导出系统的非线性运动方程,并通过在工作点附近的线性化处理,得到系统数学模型的状态空间描述。仿真结果表明,所提出的系统模型是可行且有效的。
A state-space model is necessary for designing the single-magnet controller of a magnetic levitation system. The operation principle of the system was analyzed. By the fundamental theory of classical dynamics and electromagnetics, the nonlinear motion equations were derived by using the general form of Lagrange equation. Furthermore, by linearizing the nonlinear motion equations in the operating point, the mathematical model of the system in state-space was obtained. The simulation results confirm that the model is feasible and effictive.
